Sister for Annora?

Hi
This is hypothetical at the moment, but my partner and I are really loving the combo AnnoraElspeth (nn Annie) if our first is a girl (a boy would probably be EdmundTheodore). But I'm worrying about the fact that I can't imagine what I'd name a sister. I feel like my other top favourites (Juliet and Rosa) are too common compared to Annora. I'd ideally like another unusual choice with a more accessible nickname, that doesn't begin with A; any ideas?!
Thanks in advance!
